Qn 1) What does an atom looks like? What are the sub-atomic particles inside it... (talk about electrons, neutrons, protons, electron shells, nucleus...)
Qn 2) Draw the atomic structure of a sodium atom and a sodium ion... Explain why you draw it this way.
Qn 3) Draw the atomic structure of a sulfur atom and a sulfide ion... Explain why you draw it this way.
Qn 4) Chlorine-35 atom and Chlorine-37 atom are called isotopes... Use these two examples to explain what is 'isotopes'.
Qn 5) Sodium is a metal and sulfur is a non-metal... Why do we classify them in this way?
